Hello all,
I have a situation here in Ireland, we have just got VDSL in some towns and as such good knowledge is short on the ground.
I look after the IT in two business premises and both have just had VDSL installed.
Its an industrial estate, business 1 is around 700 meters from the VDSL Cabinet.
Business 2 is around 750 - 770.
I know the exact distance as I had it confirmed by our local telecoms engineer. He laid the cable 20 years ago.
Business 1 is connecting at 25.595Mbps down 7.167Mbps up
Business 2 is connecting at 30.720Mbps down 8.191Mbps up

Stats for Business 2
I dont have enough knowledge at present to decode those numbers or more importantly why Business 1 is not getting any Signal Attenuation on the D3....
I have had the local engineer out to do a test on the line, he said if I was still not happy he would swap the current pair for another pair that the business has spare.
Can anyone point me in the right direction as to what might be wrong.....
On paper Business 1s line looks better to me......
Any help would be greatly appreciated!
